Perpetual Motion: Endlessly Rising/Falling Harmonizer

A Shepard-Risset glissando is a tone which appears to endlessly rise or fall in pitch. This is the sonic equivalent of a barber’s pole or the Penrose stairs seen in many M.C.Escher prints—an illusion of continuous directional motion. Perpetual Motion is a Max for Live device which replicates this effect to create epic risers or the feeling of eternal falling.
